I'm wondering if we can even make a difference with Joe, who is pretty powerful. If they are trying to kill him, then the killers must be pretty powerful too. Right now Oculus, Solomon, and maybe some others, I'm not sure, could be killed by a kobold. And not a particularly powerful or lucky kobold either. With that in mind, it doesn't seem particularly wise going up against opponents that can take out Joe. Plus, a wizard like Joe likely has lots of defenses in his house, and should be able to escape with his family pretty easily if threatened.
